Lexus RX350 Spare Tire
The Lexus RX350 comes equipped with a temporary spare tire, also known as a "compact" or "donut" spare. Unlike a full-size spare, this temporary tire is designed only for short-term use until a flat tire can be fixed or replaced. The reason behind this is its smaller size, lower performance capabilities, and its inability to bear weight as a regular tire. The compact spare for a Lexus RX350 typically comes in size T155/85D18, but it's essential to check the vehicle's manual or placard located on the driver's door jamb to confirm the right size. Remember that the use of the temporary spare should be limited, and the speed should not exceed 50 miles per hour to ensure safe driving.
Lexus RX350 models manufactured from 2007 to 2025 have tires with overall diameter ranging from 28.1" to 30.3", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Lexus RX350 years and trims.
Listed below are compact spare tire sizes that can fit some Lexus RX350 vehicles based on acceptable tire diameter range of 27.3" to 31.2". Some RX350 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Lexus RX350 spare tire size designated by vehicle's manufacturer.
